Abstract
An analysis employing parsimony and character compatibility methods is carried out for selected species in the various families constituting the order Boletales s.l. The results indicate that Paxillaceae is polyphyletic, actually representing a primitive matrix from which many of the other families have evolved. Gyrodontaceae is also polyphyletic, and its various genera should be included within other families. The analysis does not support that Xerocomaceae and Boletaceae should be regarded as two separate families. It indicates that the genus Suillus should be included within Gomphidiaceae. On the other hand, it strongly contradicts any relationship between Suillus and Chalciporus on one hand, and Strobilomyces on the other. The latter genus must be very isolated from the other genera analysed. The gastroid families Rhizopogonaceae and Chamonixiaceae seem to have derived from progenitors related to Boletaceae and Gyroporus (here regarded within Paxillaceae) respectively. Coniophoraceae is probably derived from precursors related to the more primitive representatives in Paxillaceae.
